A collection of light therapy research articles on the benefits of light therapy use for skin rejuvenation.
NOTE: Researchers use several terms to describe “light therapy”. Photobiomodulation, low level light therapy (LLLT), phototherapy, photon therapy, photo energy, heliotherapy, and sometimes red, blue or (near) infrared radiation are synonymous; they all refer to light therapy.
LED Light Therapy is here to stay for wound healing, pain control, inflammatory acne and skin rejuvenation
This study published by the Department of Dermatology in Kangbuk Samsung Hospital cited that if low level light therapy was delivered with an appropriate wavelength and energy density, then the potential for a significant effect exists. It was also noted that infrared light is associated with improved blood flow and neovascularization (new blood vessel growth or angiogenesis). Based on these factors, the following are the clinical applications:
- Accelerated wound healing, particularly non-healing wounds through collagen formation, with ‘quicker and better’ wound healing
- Pain and inflammation, including pain that occurs post-surgery and particularly where edema and inflammation are involved and where many states of inflammation can be significantly reduced. Human patients were presented to show the benefits on treatment-resistant inflammatory disorders
L.E.D. Low Level Light Therapy “as an adjunct to conventional surgical or nonsurgical indications is an even more exciting prospect. LED-LLLT is here to stay”.
Light therapy is a fast growing technology for stimulating, healing, and restoring the skin
Harvard Medical School Department of Dermatology is encouraging further testing of light therapy for dermatological conditions, particularly due to the “noninvasive nature and almost complete absence of side effects”. This published article goes over some of the potential benefits of light therapy for the skin including wrinkles, acne, scars, psoriasis, and healing of burns.
Light therapy effectively targets cellulite in thighs and buttocks
Cellulite is present in 90% of post-adolescent women. In this double-blind, placebo-controlled randomized trial, the treatment group was given low level light therapy (LLLT) for 30 minutes per day, three days per week, for a total of just two weeks. The researchers concluded that this was a “safe and effective for improving the appearance of cellulite in the thighs and buttocks. In contrast with other technologies, LLLT is effective as a stand-alone procedure without requiring massage or mechanical manipulation”.
